ABSTRACT:
The invention provides a novel device for separating a composite raw material under pressure into constituent flowable and residual materials. The device comprises: a laminated block having a longitudinal axis, the block comprising a plurality of transverse plates, each plate having: a first aligned bore defining an elongate collection chamber; a second aligned bore defining an elongate drain; and a transverse surface of each plate including a drainage channel extending between the first and second bores; an elongate perforated liner disposed within the collection chamber, the liner comprising a plurality of transverse planar bushings having an external surface bearing on an internal surface of the collection chamber, each bushing having: an internal aligned bore defining an elongate compression chamber; a groove in said external bushing surface defining a collection manifold between the collection chamber and each bushing; and a transverse surface of each bushing including a plurality of indentations extending between the internal bore and the collection manifold; input means for loading the compression chamber with said composite raw material; pressure means for pressurizing the raw material in the compression chamber urging said flowable material progressively through the bushing indentations, bushing collection manifolds, collection chamber, plate drainage channels, and drain, while consolidating the residual material in the compression chamber; and output means for expelling consolidated residual material from the compression chamber. In a preferred embodiment the block plates include a first aligned bore with a laterally opening plate mouth defining a precollection chamber; the liner includes bushings with a laterally opening bushing mouth defining a precompression chamber; and the input means comprise laterally actuated ram means for loading the precompression chamber with raw material with a gravity feed hopper with a lower loading chamber within which the ram means operates.
